LUOIVl FOR WEAVlNG WOVEN-WlFiE FAEFNC EJPEOIFIGATION forming part of Letters Patent No. 783,832, dated February 28, 1905.

Application filed October 8, 1903. Serial No. 176,201.

To rtZZ whom if; Hwy CON/067W)?! Be it known that we, ALEXANDER HAIDEK- Ken and Josue BERTHOTY, subjects of the Emperor of Austria-Hengary, residing at Budapest, in the Empire of Austria-I-lungary, have invented certain new and useful Improvements in Looms for the Weaving of VVoven-VVire Fabrics with Twisted arps, of which the following is a specification.

The object of the present invention is a machine for the manufacture of a fabric of woven wire the warps of which consist of two strands twisted together.

in the accompanying drawings a constructional form of the machine and a portion of the fabric produced are illustrated, by way of example, as follows: Figure 1 shows a ide elevation of the machine; Fig. 2, a detail t iereof; Fig. 3, a plan view of the left side of the machine; Fig. 3, a plan view of the right side of the machine; Fig. 1, a section on the line 1V .lV of Figs. 3 and 8, in which'portions of the apparatus have been omitted; Fig. 5, a plan view similar to Fig. 4t, but showing only the lower portions of the machine; Fig. 6, a specimen of the fabric produced; Fig. 7, a section on the line V11 VII of Fig. 6; Fig. 8, the thrower for the weft in section on the line Vlll VIII of Fig. 3; Fig. 9, the cutter for the weft in section on the line 1X IX of Fig. 3; Fig. 10, alongitudinal section of the working parts along the line XX of Fig. 3; Fig. 11, a partial view from the left side of Fig. Fig. 12, a section on the line Xll. Xll of Fig. 10; Fig. 13, a section on the line Xll] .Xlll of Fig. 10; l ig. 1a, a section on theline .IUV XlV of Fig. 10; Fig. '15, a partial front elevation of the machine viewed from the left side of Fig. 1; Fig. .16, a detail of the machine.

The warp of the fabric to be produced is composed of two wires 1, (see Figs. 6 and 7.) which are twisted together between the weft 2. The weft-wires in order to prevent any displacement of the warp are bent in an undulatory manner by the machine. The wire which serves to produce the warp runs from wirespools (not shown in the drawings) over the roller 4., revolubly journaled in the machineframe 3. (See Figs. 1, 3, and. 3b) The aforesaid roller 4: has for each warp-wire a corre sponding groove 5, in which the wire is coiled several times around the warproller. Each two wires are drawn through a tube 6, (see Figs. 3, 3, and 10,) which tube is axially adjustable in the hollow axle 7. A pin 8, fixed upon the hollow axle 7, passes through slots 9 of the tube 6 and obliges this latter to follow the revolutions of the axle '7. From the tube 5 the wires run thrtnigh a hollow axle 10, on which the revolving head 11 is placed. This latter is formed of two side pieces 12, between which are supported four rollers '13 18. In the axle 10 there is axially adjustable in the corresponding grooves 11a flat bar 15. The bar 15 is provided at its front end with an edge 16 and firmly connected at its other end with a revolubly-supported box 17. (See Fig. 13.)

The warp-wires are passed from the inner sides of the rollers 13 over the outer sides of the rollers 18,whereby in the vertical position of the revolving heads in which the double wires of the revolving heads lie in parallel planes the shed 19 is formed. Over against the revolving heads are arranged the forks 2.0, (see Figs. 3, 3, and 10,) between the upright prongs 21 of which the warp'wires can run. In front of the revolving heads are also arranged weft-wire guides, which consist of a lower part 22, formed fulincl-shaped, and an upper part 29 forming a closure.

The above-described parts, which are illustrated in Fig. 10, form the actual working and essential parts of the machine, whereas the other parts, which will be hcreii'iafter dcscribed, serve to actuate these working pa its in the required manner and at the propcrmoment and may be replaced by other equivalent mechai'iisms.

The operation of the working parts is as follows: in the position illustrated in Fig. 10 the weft-wire is carried in the manner hereinafter described through the shed, whereupon the forks are thrown forward in the direction of the arrow, and at the same time the guides 22 .33 open, and these, owing to a slight turning of the flattened axles 24 25 in the direction of the arrows 26 27, are displaced so far that the weft-wire can pass out of the guides 22. lVith the forks 20 are pushed forward at the same time the boxes 17, and with them the rods 13. The weft is carried through the fork-prongs 21 and pressed into the end 28 of the shed, which is limited by the twistingof the warp-wires resulting from the previous operation. Hereupon the hollow axles 7 and 10 fulfil their revolution all in the same direction, which takes place opposite to that in the previous operation. From this motion the two wires 1 are twisted behind the weftwire. The length over which the two wires 1 are twisted together, and thus the distance of the point 28 from the previously-passing Weft-wire, is determined by the edges 16 of the bars 15, which for this purpose remain standing from the point 28 at this distance and prevent the twisting of the wires 1 behind the edges 16. Assoon as the twisting is ended the axles 7 10 remain standing again and in such a position that the revolving heads 11 stand vertical, and the bars 15 and forks are again drawn back into their original position, Fig. 10, and the guides 22 23 are again closed. After this the above-described operation can recommence.

The finished fabric is drawn uniformly forward by means of the roller 29. This roller is provided with corresponding cross and longitudinal grooves for both the weft and the warp wires, in which grooves the said wires fit, whereby the uniform advance of the fabric is secured, Figs. 3 and 3.

The axles 7 10 are always revolved in the same direction, and as there are pegs 3O 31 inserted in the tube 6 the wires 1 are only twisted before the revolving heads 11 and behind the tubes 6, whereas between the two axles 7 10 the warp-wires always remain parallel, and thus the bars 15 can be removed to and fro without obstacle. In order that the wires 1 may be able to be drawn forward unchecked as the fabric progresses when the wires are twisted behind the tubes 6, these tubes 6 are axially adjustable in the hollow axles 7 and pressed backward by the springs 32, so that the tubes 6 are displaced forward in the hollow axle 7 whenever the wires 1 are crossed behind 'the pins 31 and are drawn forward. in the next following operation the twisting occurs in the opposite direction. Consequently the wires 1 become again parallel, whereupon the tubes 6 are again thrust out by means of the springs 32. For the production of a corresponding tension in the warp-wires there is connected with the warp-roller 4 a brake-pulley 33, against which the brake-blocks 35 are pressed by means of the band 34. The band is operated by means of the lever 36 and drawbar 37, upon the screw front end of which is placed amatrix,constructed as ahand-wheel 38.

For the operation of the above-described working parts the following arrangements are made in the constructional form illusl trated.

The shaft 39, Figs. 1 and 3,.is driven from the source of power, and this drives the shaft 42 by means of the wheels 40 41. The shaft 42 is connected with the shaft by means of the wheels 43 44. Upon the shaft 45 the cam-disks 46 are keyed. The cams 46 operate the rollers 47, which are supported in the frames 48. The said frames have a downward projection 49, which oscillates upon a pivot 50, fixed to the machine-frame, and an arm 51, projecting upward, which arm is articulated, by means of bolts 52 53, to the bars 54 55. The bars 54 are also articulated, by means of the bolts 56, to the slide 57. This latter can be moved to and fro upon two fixed bars 58, Figs. 3 and 3. Upon the slide 57 the boxes 17 are revolubly supported. (See Fig. 10.) By the revolution of the cams 46 the frame 48, with arm 51, is set in oscillation around the pivot 50, so that the slide 57, with the boxes 17 and bars 15, is moved to and fro. The shape of the cam-disks 46 is such that the bars 15 receive the desired motion, whereby the stoppage of the bars 15 by concentric portions of the cams 46'is attained. The bars 55, connected with the arm 51, are also connected with the levers 59, Figs. 1, 2, 3, and 3, which oscillate upon the pivots 60. At the upper end of the lever 59 is arranged a slot 61, in which the bolt 62 of the slide 63 engages, so that by the oscillation of the lever 59 the slide 63 is moved to and fro upon the bars 58. Upon the slide 63 are fixed the forks 20, Figs. 3, 3, and 10. The bars act upon the levers 59 by means of springs 64, Figs. 1 and 2, so that on the displacement of the bars 55 first the springs 64 are a little pressed together and then the levers 59 swing forward. For this purpose there are fixed upon the levers 59 the bolts 65, which slide in slots 66 of the bars 55.

ith the.lever 59 a bar 67 is articulated, which bar slides in a hole of the block 68. This block 68 is adjustable upon the bar 55 and can be fastened in place by means of the set-screw 70 passing through the slot 69. This spring transmission of the motion from the bar 55 to the lever 59 has the object of pressing the weft-wire into the fore end 28 of the shed, oven in the case when the bar has already ended its forward motion and remains awhile stationary, while the fabric is drawn forward by the continuous turning of the roller 29, Figs. 3 and 3, whereby the springs 64 push the levers 59 a little farther, and the forks 20 press the weft-wire correspondingly forward.

For the purpose of turning the hollow axles 7 10 the following arrangement is devised: Upon the axle 45 is placed the cone-wheel 199, Figs. .1 and 3, which engages with the l wire runsfrom aspool (not shown in thedrawlugs) between guide-rolls 195 to the gear corresponding wheel 179. The latter is fixed upon the axle 71, Figs. 1, 4:, and 5, which axle is supported upon the cross-bars 72 of the machine-frame. Upon the axle 71 is placed a gear-wl'ieel 73, Figs. 1 and 5, which wheel drives the axle 78 through the wheel 71, shaft 75 and gear-wheel 79 77. Upon the axle 7 8 is placed a cam-disk 79, which acts upon two rollers 81, supported in a carriage 30. The carriage 89 runs upon four wheels 92 in a guide 83, which is fastened. upon the cross-piece 72. With the carriage 89 there is connected a guide-rod 8 1, which operates the toothed segment 89, oscillating upon the pivot The toothed segment 89 is connected with a gear-wheel 87, Figs. 3 and t, upon the shaft whereof, 89, is placed a gear-wheel 89. This latter is in connection with a gear-wheel 99, upon the axle 91 of which the cone-wheels 92 93 are keyed. The cone-wheels 92 93 gear with the cone-wheels 9 1 95, which are keyed upon axles 96 97. Upon these axles are keyed the worm-wheels 98 99. (See Figs. 3, 3, 1, 19, 12, 141.) by 111021118 of the wheels 98 99 the hollow axles 7 19, provided with corresponding gear-wheels 199 191, are driven. By'the turning of the cam-disk 79, Fig. 4:, the carriage 39 is moved to and fro in the guide 33, wl'iereby the toothed segment 39 is oscillated and the axles 88 91 are revolved. The turning of these axles is transmitted through the cone-gearing to the axles 99 97 and from these through the worm-gearing to the hollow axles7 19. The stoppage of the hollow axles is effected by means of a correspondingly-concentric part of the cam-disk 79. By means of a slot 192 in the toothed segment 89, in which the guide-rod 3 1 can be adjusted, the angle of oscillation of the toothed segment, and consequently the number of revolutions of the hollow axles 7 19, can be adjusted. The transmission of the gear-wheels 73 7 1 and 79 77 is so proportioned that the number of revolutions of the axles 7b is one-half that of the axle 71, because the latter axle at each working stroke completes an entire revolution, whereas the axle 7 3 at each working stroke only completes half the revolution in the manner that the carriage is pushed by the camdisk 79 in every proceeding from right to left and in the next proceedingfrom left to right, so that the gear'wheel 87 is rotated by the tootl'ual segment 1'39 in one proceeding in one direction and in the next proceeding in the other direction, whereby the warps are twisted between the weft-wires alternately to right and left.

The weft-thrower consists, essentially, of the two wheels 193 194, Fig. 8, which are set in motion at the required moment, project the weft-wire through the guides 22 23, and at the same time give it an undulatory curvature in the manneralread y well known. The weftwheel 193 191 and from here through a hole 199, Figs. 3 and 9, which is arranged in a. PI'OjPCt-lOTl 197 of the support 198 of the flattened axles 241 25.

In a dovetail guide 199 of the journal 198 is placed a knife 119, which is held by means of a spring 111 in the inner position. (Shown in Fig. 9.) Upon the knife there is a projection 112, behind which engages a catch 113, iixed upon the axle 25. In consequence of-the angular revolution of the axle 25 on the opening of the guides 22 23 the projection 113 presses the knife 119 forward, whereby the weft-wire is cut off at the hole 199, so that the wcft-wire lying in the guides 22 23 can be drawn unhindered by the forks 29.

The angular revolution of the two axles 24 25'is effected by means of a rod 114:. Figs. 3, 19, lixed to the slide 57, Figs. 3 and 3. This rod is arranged to press two cranks 119 apart (which cranks are keyed upon the axles 2 1 25) by means of its wedge-shaped end 115 when the slide 51 advances. The cranks 119 are provided with antifrictimi-rollers 117. When the slide 57 retreats, the cranks 119 are drawn back by the springs 197, and the axles 2-1 29 return to their original position.

The actuation of the weftthrower is effected by a cam-disk 118, lixed upon the axle 71, Fig. 4, which disk acts upon two rollers 129 in a frame 119, and thereby causes the frame to oscillate upon a pivot 121. The oscillation of the frame is communicated, by means of the rods 122, to a toothed segment 121, oscillating upon an axle 123, which segntient engages with a gear-wheel 125. (See Figs. 1, 3, 1, 8.) The gear-wheel 125, revolving loose upon the axle 129, is connected with astud 127, in which is located a catch 129 upon the pivot 128. The catch 129 is pressed by a spring (not shown in the drawings) upon the ratchetwheel 139, keyed upon the axle 129, so that the turning of the wheel 125 in the direction of the arrow at, Fig. 1, is transmitted, through the catch 129, to the ratchet-wheel 139, and consequently to the axle 129, whereas at the following revolution ofthe geauwheel 125 in the opposite direction the catch 129 slips over the teeth of the ratchet-wheel 139 without causing the axle 129 to revolve. The periodic turning of the axle 129 is transmitted, by means of gear-wheels 131 132, to the axle 133 of the gear-wheel 193. The axles 133 and an of the gear-wheels 193 104 are connected by Figs. 3 and 3, which are placed upon two axles 138 139, Fig. 1. Upon the axles 138 139 there may be also further cutters 140 placed if it is necessary to cut the fabric in various places.

The finished fabric is rolled up upon a roller 141, which is driven by interposition of a friction-coupling in order to avoid increase of tension as the diameter of the roll of fabric increases. For this purpose there is keyed upon the axle 78 acone-wheel142, which drives the axle 144 by means of cone-wheel 143. The said axle drives, through the sprocket-wheel transmission 145 146, Figs. 1 and 3, the disk 148, placed loose upon the axle 147. Upon ,the axle 147 there is further placed a disk 150,

provided with friction-clutches 149, which is connected with a gear-wheel 151, which wheel drives the roller 141 through the wheel 152. The disk 148 is pressed against the clutch 149 by means of an angle-lever 154, supported in the block 153, Fig. 15. The amount of the pressure can be adjusted by means of the handwheel 155. The limb of the lever 154, which acts upon the disk 148, is forked, and each limb of the fork is provided with an antifrictionroller 156, Figs. 3 and 15.

The roller 29 is driven from the axle 144, Figs. 1 and 3, and then through the toothwheels 157 158 159 160 161 162. The axles 138 139- of the circular cutters are driven by the rollers through the gear-wheels 163 164 165 166.

Having now particularly described and ascertained'the nature of our said invention and in what manner the same is to be performed, we declare'that what we claim is 1. In a machine for producing a woven wire fabric having a warp consisting of twisted wires, the combination with a roller, of revolubly-supported shed-forming heads held against axial movement, and bars adapted to revolve with said heads and capable of axial movement in the direction of the warp-wires, the free ends of said bars being so arranged as to limit the length over which the two wires of the warp are twisted together.

2. In a machine for producing a woven-wire fabric, havinga twisted warp, the combination with a roller and revolubly-supported shed-.

forming heads for the warp-wires of supporting-forks adapted to throw forward the weftwire inserted in the shed and to press said wire into the end of said shed.

3. In combination with a weft-thrower as above set forth, weft-guides between the warpwires consisting of funnel-shaped forks and closing-pieces covering the opening thereof, which parts open when the weft is pushed forward, substantially as set forth.

In testimony whereof we aflix our signatures in presence of two witnesses.
